MasterFiber 051

Synthetic Fibrillated Microfibre for the Reduction of Plastic Shrinkage Cracking and Improved Impact Resistance of Cementitious Mixes

How Does MasterFiber 051 Work?

MasterFiber 051 is a fibrillated microfibre made from 100% virgin polypropylene specifically engineered to be used for the reduction of plastic shrinkage cracks, and to improve impact resistance in cementitious applications. MasterFiber 051 can be used in all concrete works where problems due to plastic shrinkage and/or inadequate curing cause cracking.

MasterFiber 051 conforms to the requirements of EN 14889.2 Class Ib.
